I mean did we ever have to learn any of this, get an education all we needed was food, water , and a place to live not rocket science.

Seems like we are going into the meaning of life here... By your logic then: Do we need food or water? Why do we need to survive? If we have no reason to survive other than to survive and reproduce then why survive?... Think harder. Think past what you have been told or past the simple puzzle pieces you have assembled in your head.

Did we need railroadtrains,cars, airplanes,boats,and for that matter did we ever need to travel by air,or sea.

Yes. Or maybe you should have asked: Are humans curious? ...same answer - same question

don't think i'm a nerd or anything or a loner i play football,and other stuf like other kids

Ahh i love primordial instincts. "im really strong, i can catch many buffalo"If by definition a nerd is one who thinks about things then i am definately a nerd. Dont let cultural notions and attitudes sculpt your ideologies, keep thinking and learning.

Did we ever have to have asthma,no, well we sort of created it i mean almost every kid has asthma because of pollution and all that.

Umm...No.-Genetic factors-Environmental factors-Dietary changes-Lack of exercise-Occupational exposureNote that the environment is 1 factor.

Where are you getting all these little things from? Science is 10% persuasion 90% evidence - not the other way around. Sorry if i get a little worked up on doomsday-negative nancy issues.

A wise man once said to me:"Build a man a fire, and he'll be warm for a day. Set a man on fire, and he'll be warm for the rest of his life."

In some countries ,like china, government is trying to control the population cause they're faced with lack of sources and in some European countries they're encouraging couples to have babies!What happens to be the reason? The weather!? really, is there a reason related to geography or not?

No, the reason is, how much developed is the country and the density of population.About the first, someone already spoke here. E.g. the European countries (the native population) is decreasing, as we do not have so many babies etc..., on the other hand, the Arabian world is still growing, and their population is also growing in the Europe...About the first, if you had population of China (1.3 billions or more now?) spread all over the world, than you won't have any problem with the same number of people, whit which they have problem now. If you put the whole population of US to e.g. New Zealand, than you will have definitelly problems, althrough Americans live now quite well

Well, don't you consider china a developed country?I guess it's mostly based on the cultures & the culture of a country is related to geography things. Those from warm places are usually much lazier! (I'm not joking)
